CosineWindow

CosineWindow[x] represents a cosine window function of x.

CosineWindow[x, α] uses the exponent α.

Examples

Plot a cosine window:

Plot[CosineWindow[x], {x, -1, 1}]

Apply to signal processing:

data = Table[Sin[2 Pi t/10], {t, 0, 99}];
ListLinePlot[data * Table[CosineWindow[t/50 - 1], {t, 0, 99}]]
